One of the more interesting diet myths came from the Saxon Brothers that were very famous back in their day, here's an except-
"
For breakfast they ate 24 eggs and 3 pounds of smoked bacon; porridge with cream, honey, marmalade and tea with plenty of sugar. At three o'clock they had dinner: ten pounds of meat was consumed with vegetables (but not much potatoes); sweet fruits, raw or cooked, sweet cakes, salads, sweet puddings, cocoa and whipped cream and very sweet tea. Supper, after the show, they had cold meat, smoked fish, much butter, cheese and beer. Following this they had a chat and at one o'clock went to bed. " .
And their heath drink-
" The Saxons did have a "health drink" which I presume they concocted themselves. The ingredients were dark lager beer (or Dublin stout) mixed with Holland gin, the yolk of an egg and plenty of sugar. "It is a very good but strong drink" was the Saxon opinion, "but, if you are not used to it you will get dizzy very quickly." .
